METAL CARRIER FOR WASTE GAS CLEANING CATALYST

PURPOSE:To prevent rupture of a honeycomb part by inserting a reinforcing wavy sheet with a specified thickness between the outer surface of the honeycomb part and the inner surface of an outer cylinder encircling the outer surface of the honeycomb part. CONSTITUTION:Circling at least one circle of the outer surface of a honeycomb part 1, a reinforcing wavy sheet with a thickness thicker than those of a platy sheet 10 and a wavy sheet 11 of the honeycomb part 1 and thinner than that of an outer cylinder 3 is inserted between the outer surface of the honeycomb part 1 and the inner surface of the outer cylinder 3. By this structure, convergence of stress caused by difference of coefficients of thermal expansions and temperature distribution of the honeycomb part and the outer cylinder is moderated. Rupture of the honeycomb part is thus prevented.
